Louisiana Doesn't Certify Your Assessment Roll Until October 20, Five Weeks After Your Appeal Window Already Closed.

Updated August 2026

Louisiana's appeal season nominally runs from around August 1 to September 15, but for most of that window there is nothing to look at. Parish assessment lists don't open for statewide public exposure until August 15 (earlier in Orleans and Jefferson parishes), under La. Admin. Code tit. 61, Part V, Section 3101. That leaves you a roughly one-month look-then-file period, inspect the assessor's numbers and decide whether to fight them, packed inside a window that's already closing. And the roll you're looking at during that month isn't even final: it doesn't get certified to the Louisiana Tax Commission until October 20, more than a month after your own appeal deadline has passed.

That sequencing quirk matters because Louisiana reassesses on a quadrennial cycle, once every four years, administered parish by parish under La. Const. Art. VII, Section 18(A)(1) and La. R.S. 47:2331. Get a reassessment year wrong and you're not just off for twelve months, you're off for up to four years until the next cycle resets the number. Meanwhile your mortgage servicer is watching none of this. It runs its own escrow analysis on a federal calendar, set by Regulation X, that pays whatever the parish bills, appeal, certification date, and quadrennial cycle notwithstanding.

What Over-Assessed Actually Means in Louisiana

Louisiana taxes residential land and improvements at 10% of fair market value under La. Const. Art. VII, Section 18(B). That 10% ratio is uniform statewide, so the number that actually drives your bill is the fair market value your parish assessor puts on the roll, the figure you can only see once the exposure period opens on August 15.

Because Louisiana reassesses quadrennially rather than annually, a parish's assessed values can sit unchanged for three years and then jump all at once in the fourth. If that jump overshoots what your home would actually sell for, you're carrying an inflated value not for one tax year but potentially for the whole remaining stretch of the four-year cycle, until the next reassessment or a successful appeal corrects it. That's what makes the short look-then-file window so consequential: a missed deadline in a reassessment year isn't a one-year mistake, it's a multi-year one.

Four Levels, and Your Servicer Is Tracking None of Them

Once you've filed, Louisiana's appeal path has four possible stops. Most cases resolve at the first or second level, but a contested valuation can climb all the way to court:

1. Parish Assessor (Informal). After the rolls open for exposure on August 15 (earlier in Orleans and Jefferson), your written complaint must reach the assessor's office within three business days after the exposure period ends, under La. R.S. 47:1992. Many disputes are resolved here without ever reaching a board.
2. Board of Review. If the assessor's office doesn't resolve it, the assessor forwards your complaint to the parish Board of Review within seven business days. The board must convene hearings on or before September 15, the same date your original appeal window closes.
3. Louisiana Tax Commission. Under La. R.S. 47:1989, the Commission hears appeals from a Board of Review's decision, but it can't schedule that hearing until it receives the parish's certified assessment list, which doesn't happen until October 20 at the earliest. The Commission then has 10 days from receiving that certified list to hold hearings. A Board of Review decision from mid-September can sit waiting on the Commission's docket for a month or more simply because the underlying roll hasn't been certified yet.
4. District Court. Under La. R.S. 47:1998, a taxpayer dissatisfied with the Commission's final decision has 30 days to file suit in district court. Civil litigation runs on its own calendar and an uncomplicated valuation dispute can still take months to resolve.

Notice what none of these deadlines depend on: your mortgage servicer. Nothing in La. R.S. 47:1992 or 47:1989 requires anyone to notify the loan servicing side of your mortgage that a valuation is under dispute. That notice, if it happens at all, comes from you.

Meanwhile: The RESPA Clock That Doesn't Care About Your Parish's Certification Date

Federal law, not Louisiana law, governs your escrow account. Under Regulation X, 12 CFR 1024.17(c)(3), your mortgage servicer must run an escrow analysis once per computation year, a twelve-month cycle tied to your loan, not to your parish's reassessment calendar. That analysis looks at what the servicer actually paid the parish and projects what it expects to pay next. It does not check whether a Board of Review hearing is pending, whether the Louisiana Tax Commission has your certified roll yet, or whether a quadrennial cycle just reset your value. It pays whatever bill the parish sends, off whatever value is on the books at the time.

So if you filed with the assessor in late August, lost at the Board of Review by September 15, and are still waiting for the Louisiana Tax Commission to even receive your parish's certified list on October 20, your escrow account has almost certainly already funded that year's tax bill at the original, disputed value, months before your case has a realistic shot at resolving.

A worked example (hypothetical, not a real case)

Say a homeowner in East Baton Rouge Parish owns a home the assessor lists at Louisiana's median, $174,000, in a year the parish is running its quadrennial reassessment. At Louisiana's 0.55% effective rate, that's roughly $957 in annual property tax, or about $80 a month if spread evenly through escrow. (Millage rates vary by taxing district, so treat this as illustration, not a quote.) She believes the true value is closer to $151,000. The parish's rolls open for exposure on August 15; she visits the assessor's office that same week, pulls her own comparable sales, and files a written complaint before the three-business-day window under La. R.S. 47:1992 closes. The assessor doesn't budge. She escalates to the Board of Review, which hears her case and rules against her by mid-September. She appeals to the Louisiana Tax Commission, but the parish's list isn't certified until October 20, so the Commission can't calendar her hearing until after that date. Her case is finally heard in early November.

• Year one, tax bill: Escrow pays the full $957, based on the original assessed value, because the parish's bill went out in December before her Tax Commission hearing had even happened.
• Year one, escrow analysis: No change. The analysis simply confirms the servicer paid what the parish billed.
• Tax Commission decision, say a 13% reduction: New fair market value roughly $151,380, new annual tax roughly $832, a savings of about $125 a year.
• Because this is a reassessment year: The corrected value generally carries through the rest of the four-year cycle, not just this one bill, under La. Const. Art. VII, Section 18(A)(1) and La. R.S. 47:2331.
• Refund and go-forward adjustment: Only happens at the next escrow analysis after the parish issues a corrected bill and the servicer actually processes it.

A case she filed within days of the rolls opening still didn't reach a Tax Commission hearing until three months later, purely because of the certification calendar, and her escrow account had no way of knowing any of it was happening.

When the Win Finally Reaches Your Escrow Account

Whichever level finally rules in your favor, the mechanics from there are the same. The assessor updates the roll with the corrected value, the parish tax collector issues a corrected bill (or a refund, if the disputed amount was already collected), and none of that touches your monthly payment on its own. Your servicer has to see it. Three federal rules in 12 CFR 1024.17 control what happens next:

• The surplus rule. If your next analysis shows a surplus of $50 or more, the servicer must refund it within 30 days, provided you are current on the loan (Section 1024.17(f)(2)(i) and (f)(2)(ii)).
• The cushion cap. Servicers can hold a cushion of no more than one-sixth of estimated annual disbursements, roughly two months' worth (Section 1024.17(c)(5)). A lower tax bill shrinks the allowed cushion too, which is often why a post-appeal refund is larger than the tax savings alone.
• The off-cycle option. A servicer is permitted, not required, to run an analysis outside the normal annual cycle (Section 1024.17(f)(1)(ii)). Send them the parish's corrected bill and the Tax Commission's decision and ask; you have nothing to lose, and the annual analysis will catch it either way.

If your case went all the way to the Louisiana Tax Commission or district court and took months to resolve, don't assume your servicer is tracking it. Nobody in the escrow department is watching your parish assessor's certification calendar. The corrected bill from the parish is the document that actually moves your payment, so keep a copy of the ruling and the revised assessment, and send both the moment they arrive.

The Five-Week Window You Actually Control

Everything after your initial filing runs on a calendar set by someone else. The Board of Review's hearing dates, the Louisiana Tax Commission's October 20 certification dependency, a district court's trial calendar, and your servicer's own escrow computation year are all fixed by parish, state, and federal schedules you don't control. The one date that is entirely yours is the moment the exposure period opens on August 15 and the roughly one-month clock starts running toward your September 15 deadline.

If you wait to see the assessor's numbers before you start pulling comparable sales, you've already burned into a window that was never long to begin with. Have your evidence ready before the rolls open, so the only thing left to do in that five-week stretch is file.

Key Parishes

The highest-volume appeal jurisdictions in Louisiana are East Baton Rouge, Jefferson, Orleans, St. Tammany, and Caddo parishes. Orleans and Jefferson open their public exposure period earlier than the rest of the state, so their look-then-file window (and the deadline that follows it) can start sooner than the statewide date. Filing procedures, hearing schedules, and local practice vary by parish even though the statewide certification date and RESPA rules apply everywhere, so confirm the exact exposure dates with your specific parish assessor before you plan around them.
